OH I just had a AHA moment. you have the bespoke tunes from Randy ? I would contact them (Mountune) First as that may be tied to the AP and is the ATR software . I am not sure but I would ask first to be sure ..

I talked to Cobb and to Randy, I have the Cobb version with Randy's tune but it is not their proprietary software so good to go.

I just bought the tuner race software so now I can tune as most of it is figured out, just make the changes and then fine tune on the road then get on the dyno so I can post some catted DP, 5000 ft elevation, 91 octane numbers:)

----------

Got the gauges to work, called Cobb, walked me through it and it worked right away doing exactly what I had been doing but I was dead tired when I first tired and several more times including this morning....so maybe I was just being stupid.

I powered it down after the firmware update, several times, etc....just one of those things it seems.

Just finished the final tweaks on the alignment, now I have very very tight tolerances where I wanted them.

Front
-2.5 camber
Zero toe
Castor increased but my gauge needs a new batter, it will be about 2 degrees more than stock

Rear
-1.5 camber
Zero toe

Front to rear tracking angle factory tolerance is +- 0 to .50, mine is less than .08

The car is not slammed, just low enough to really work and looks great as well, so the roll center, roll couple, bump steer, all the really important stuff most do not consider are all great.

TO THE POINT, I got on it a bit, wow, even 70% throttle and shifting at 5k it pulls very very well, not even a hard shift and it chirped the tires in third on sticky cement. It has a very wide torque curve now so will have power where needed far more of the time.

I need to pound on some miles in the next couple of days as will be tuning it and want it ready when I go to MMP on Monday for the Academy, they want to check it out:)

Just got back, 200 plus miles through the back woods mountain roads checking out the fall colors, perfect way to get more breaking in miles and incredible views. Around 45 miles was on the freeway, average speed was just 35MPH so you know the roads were narrow and twisty and quite a bit of traffic but I was just chilling and enjoying the time.

The car is so perfect for that, tons of room, comfy, easy to drive, easy to see out of, we love it!

I goosed it here and there and with just the MT tune it is very peppy in the mountains.

32.2 MPG average for the trip, cannot complain about that when up and down three mountain passes, lots of second gear and some third and a few 1st gear corners.

Only a few times did I have to down shift for more power and it was only out of very slow corners where any car would have to downshift.

The power band is so much better than the stock turbo as have power most anywhere in the rev range.

Even when my car was just stage 1 did I rarely ever find myself downshifting due to lack of power..

My car is not tuned for this turbo, it has an OTS tune for the stock one, TBE and that is it.

I was also as high as 8k ft, lowest was around 4600ft, over three passes, etc...some corners so steep and tight I do not think I could drive my dually around them without backing up a few times and the ST felt like I was going to bottom out many times on the front bumper.

It was 90 degrees in the lowest area and 63 on the top, oil temp never went past 205 degrees, water temp less than 200.

The mountains in UT are a bit more severe than most of the US, one section they call the Alpine Loop for good reason, look up Sundance ski resort and see what it looks like in that area!!

I have to admit... My car went from basically neutral to "kinda scarey" in about 3 days... I can't imagine with Ricks eye for detail, plus a nice intercooler how his car is going to be on full boil, lol.
What'd you say your car would trap as it sits? 103-105ish?

As it is it has a nice amount of power to make it easy to drive, snappy but not fast, but then again I have not really opened it up, shift early, etc...due to now just having 640 miles on it!

Big storm rolling in, if not for that I would make it over 1k miles tomorrow then start the real tuning after an oil change of course.

"Dynos or ban Rick"

Let's see, dynos are so important, like the last two I had done led to blown engines by "experts"....real world driveability, power to fit the build and purpose of the car, that is all I care about, I am only going to get a dyno run mostly to help SS show what this can do but I am curious so will take the time to get it done.

Of course I like to talk about power and am impressed by big numbers but I also realize the whole car is just as important. Balance is the only thing I am after, I build the car for what I want it to do and do it well in all areas then stir in the power to balance it out.

A bit of reserve is nice for special occasions but a bunch of power in a less than well sorted out car is to me mostly useless.

It helps the ST is a great car completely stock but it has shortcomings I felt were more important to fix first then upgrade areas I want to work better then add in the power.

Using this formula I have beaten hundreds of cars with more power as it was their primary focus.

Far to many spend their time on bragging rights than on a well sorted and balanced package even when doing suspension, brake, etc upgrades.

Haha
Being as my friend just trapped 100mph on a stock turbo, yea... I'd expect 103-105mph if I spun enough and my motor mounts didn't shatter again.
Nice!

If the car doesn't sell soon I'm getting a custom tune done on some form of ethanol E50/85(if the pump will support it) and really hoping to get back out and hit a 105mph trap on a 100% stock turbo. Think for this season 13's are a bust due to traction or lack thereof.

Really?? I just went almost 102 on 93..

You can get away with not having "as much" intercooler with an ethanol setup though with its cooling properties, but I don't have to tell you that lol.
